Type material.

Holotype, male, ( NECJU 201809) CAMEROON, Bamboo Camp, 350 m a.s.l., Mount Cameroon (SW slope), N4.08791°, E9.05051°, 17.-23.IV.2015. V. Maicher, Sz. Sáfián, Š. Janeček, R. Tropek. Paratypes: 1 male, 2 females ( NECJU, CUK), same data as holotype; 1 male (CUK), PlanteCam, 09-14.IV.2015, V. Maicher, Sz. Sáfián, Š. Janeček, R. Tropek.

Diagnosis.

The mottled yellowish brown wings of the new species have some similarity to A. lidiya  , but these species differ from each other by the narrow medial band and the dark-brown spots in the apical parts of the lobes in A. olga  . In the male genitalia, the shapes of the uncus, saccus and phallus of A. olga  are similar to A. spicifera  Meyrick, 1911. These species differ from each other by the wide, oval gnathos and the short valva not widened distally, in A. olga  , and by the gnathos and valva widened at the apices in A. spicifera  .

External characters.

Head, thorax and tegula with brown-yellow clinging scales. Labial palpus spotty, with alternating white and black scales, 2 × longer than longitudinal eye diameter, bent upwards. Third segment long, thin, tapered to apex. Antenna yellow, interspersed with dark brown scales. Wingspan 10-11 mm, of holotype 11 mm. Wing mottled, yellowish brown. Wing base coloured with dark brown scales. First lobe of fore wing with well-expressed orange elongated spots, alternating with dark brown elongated spots separated by white bands. Alternation of orange and dark brown spots on other lobes of both wings. Apical area of all lobes ends with dark brown spot. Fringe on wing yellowish brown, with alternating portions of pale and brown hairs. Hind leg pale yellow.

Male genitalia.

Uncus medially narrow, distally widened, apex with four claw-like processes forming a kind of rake. Gnathos wide, oval. Gnathos arms straight, narrow, apically tapered. Valva quite wide, short, membranous, poorly sclerotised. Anellus arms long, wide. Saccus slightly elongated, oval. Phallus narrow, elongated, longer than entire genital structure, with one well-expressed narrow long cornutus and cluster of small needle-shaped cornuti distally.

Female genitalia.

Papilla analis elongated, narrow triangle. Posterior apophyses thin, straight. Anterior apophyses thin, slightly longer than posterior apophyses. Antrum wide, funnel-shaped, sclerotised. Ductus wide, short, narrow at confluence to bursa copulatrix. Ductus seminalis short, wide. Bursa copulatrix big, oval, with two narrow longitudinal ribbon-like signa, impregnation of many small spines inside the whole bursa.
